Temperatures could be from ambient to 100 deg C

Hello, Apologies for banging in a question on my first post, but I am at a loss with my research. I am a designer, and am looking at using a ceramic tube as a pressure vessel. This vessel will be pressurised to 5000psi (~340bar). I need to place this ceramic within another material that will contain it in the chance that the ceramic fails catastrophically. I cannot use metals as they are conductive. Originally I have looked at another ceramic tube lined with ptfe (teflon). This worked 2 in 3 times, I need something more fail safe however. Hoping someone can help, Ginge
